Hi all,
Which command is to be used to check all virtual IP's of interface?

ifconfig shows only real ip's.
tx.

ifconfig -a should show you all ips and vips and their status.

no,

linux:~ # cat /etc/sysconfig/network/ifcfg-eth0
BOOTPROTO='static'
BROADCAST='172.16.1.255'
IPADDR='172.16.1.3'
MTU=''
NETMASK='255.255.255.0'
NETWORK='172.16.1.0'
REMOTE_IPADDR=''
STARTMODE='onboot'
_nm_name='static-0'
linux:~ # cat /etc/sysconfig/network/ifcfg-eth1
BOOTPROTO='static'
MTU=''
REMOTE_IPADDR=''
STARTMODE='onboot'
_nm_name='static-0'
IPADDR_2='172.16.2.1'
NETMASK_2='255.255.255.192'
IPADDR_3='172.16.3.1'
IPADDR='172.16.3.5'
NETMASK='255.255.255.192'
NETWORK='172.16.5.0'

BUT ifconfig -a doesnt show all ip's of eth1 as given below

eth0 Link encap:Ethernet HWaddr 00:30:48:52:CC:06

Which Linux are you using, btw?

In RedHat, I've set up separate files. For example:

# cat /etc/sysconfig/network-scripts/ifcfg-eth0:1
DEVICE=eth0:1
BOOTPROTO=static
IPADDR=192.168.30.127
NETMASK=255.255.255.0
NETWORK=192.168.30.0
BROADCAST=192.168.30.255
ONBOOT=yes

And I believe you can set them up in the same file as you were trying, but you have to have multiple "Device" entries.
